Adjustable displacement perception compensation golf putter apparatus and method

ABSTRACT

A method to reduce parallax effect and reduce aiming error while a golf player is putting is disclosed. The player positions a golf putter along a first selected alignment marker to align a multi-alignment marker golf club with a line of putt. Aiming along the first selected alignment marker of the golf putter body, the player perceives correct alignment, but actual results in an alignment error to the line of putt. After receiving feedback (from coach or self), a second selected alignment marker is chosen. The player positions the club face along the second selected alignment marker to the line of putt and the result is evaluated. The alignment marker selection process repeats until the player finds a marker that achieves a consistency of aiming that aligns a club face along the line of putt.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates generally to the field of golf equipment and assemblies, and specifically in one exemplary aspect to an adjustable golf putter apparatus and method to improve targeting and aiming accuracy.

2. Description of Related Technology

Golf equipment and assemblies are well known in the art. Such assemblies are utilized to improve golf shots of players. Golf is a strategic game that involves hitting accuracy both in the long game (e.g., off the tee) and the short game (e.g., once on the green). The main difference between a high golf score (over 100) and a low golf score (less than 80) equates to player consistency and accuracy. One way to lower a player's score is to improve aiming accuracy of a golf club putter along a selected line toward the hole while in the short game. Golf coaches instruct their students that the key to successful putting and choosing a desired line is proper and consistent face alignment (aiming) to hit the ball on the desired line.

However, even with this instruction, more than 9 out of 10 players don't properly aim at the target and most are off by several degrees, which is enough to miss an important putt causing a higher golf score. Why are players off with aiming? Why are players with a great stroke still missing the target? A study of the United States Golf Association (USGA) rules of how a player may address the ball provides insight into the golf putting aiming issue. USGA rules, for instance, rule 16-1 recites:

“a: Touching Line of Putt: The line of putt must not be touched except:

-   -   (i) the player may remove loose impediments, provided he does         not press anything down;     -   (ii) the player may place the club in front of the ball when         addressing it, provided he does not press anything down;

e. Standing Astride or on Line of Putt. The player must not make a stroke on the putting green from a stance astride, or with either foot touching, the line of putt or an extension of that line behind the ball.” As a result, a player standing astride is forced to stand in a side address position relative to a line of putt.

In complying with USGA rules, players experience a built-in perception skew or “parallax” in their relative perception with “of the location” of target golf hole caused by a side on address position. Even with hours of practice and emphasis on perfect golf mechanics and form, many players fail to reduce their golf putting score because repetitive practice with numerous conventional golf putters don't compensate for perception inadequacies associated with “side-on” viewing of the target. In other words, players who have developed a great golf putting stroke may be focusing their efforts on an aspect of putting that doesn't result in a marked improvement.

Why is aiming so important? Studies by golf professionals have shown that approximately 90% of aiming error associated with the golf putter transfers to how a golf ball rolls toward a target golf hole. In contrast to an aiming error, golf professional studies illustrate that only 15% of a path error transfers to how a golf ball rolls toward a target golf hole. As a consequence, any reduction in aiming error will result in significant improvement (a lower golf score) for all levels of players when putting toward a target golf hole. Golf instructors report 2, 3, or 4 degree aiming errors as common for players of all skill levels. Aiming errors (e.g., angle errors, golf club face alignment) become even more significant further a player is from a target golf hole.

Using a center line that is perpendicular to a face of the club, various testing experiments have demonstrated 9 out of 10 players did not line up correctly and exhibited aiming errors when aligning the face of the golf putter with the target. With standard USGA target golf hole size of 4.25 inch diameter (2.125 inch radius from dead center), aiming errors between the golf club face with the target golf hole cause an increasing number of misses between the target and the golf ball as the golf club face is positioned further from the target, e.g., a two degree aiming error results in a target miss for a golf hole located at 6.3 feet away; a three degree aiming error results in a target miss for a golf hole located at 3.76 feet away; and a four degree aiming error results in a target miss for a golf hole located at 2.82 feet away.

Using a conventional golf club, players align the golf putter to the target golf hole using binocular vision, e.g., through two eyes. However, binocular vision does not produce a true location of the relative spatial angle of the golf club face to the target golf hole because each eye of a player perceives a distinctive directional and alignment information for hitting the golf ball toward target golf hole. In one instance, a player's left eye (due to positioning on face, relative viewing angle to the target, and dominance in far or near sighted capability and/or as relative to right eye visual capabilities) perceives a first desired hitting location right of target golf hole. In yet another instance, a player's right eye (due to positioning on face, relative viewing angle to the target, and dominance in far or near sighted capability and/or as relative to left eye visual capabilities) perceives a desired hitting location left of a target golf hole. Finally, both right and left eyes (due to dominance of one or both in near and far sighted capability as well as positioning) to cause a third desired hitting location for alignment of golf club face to hit the golf ball toward a target golf hole. Consequently, disparate directional information from one or both eyes (either alone or in concert therewith) result in a “parallax” or skewed viewing perception that causes alignment errors of a golf putter face relative to a target golf hole.

Conventional patented golf putter technologies teach and suggest a desirability to choose perpendicular alignment of a golf putter face toward a target golf hole and align a golf putter face along a chosen golf ball path alignment to achieve golf putting accuracy. For instance, U.S. Pat. No. 4,659,083 by inventor Sczepanski discloses a desirability of perpendicular alignment of the club face with that of a target golf hole using a multitude of directional indicia oriented to the path of movement of the face of the club. In yet another instance, U.S. Pat. No. 4,291,883 by inventor Smart discloses a desirability of correcting golf ball path error using a primary plate with a removable sight rod and a number of recesses in the plate, for setting the angle of a directional rod and to direct a player's golf swing along a desired path toward the target golf hole.

In contrast to conventional golf putters and golf ball alignment procedures, a golf putter and golf putter alignment process may further be desired to reduce the parallax problem (e.g., human binocular vision problem). For instance, novel design golf putters and golf putter alignment processes may further provide a wider variety of user adaptability and/or improved user accuracy as well as provide various types of and configurations that are adjustable to fit a user without requiring complicated attachment/de-attachment hardware. For instance, a manufacturer or user may find it beneficial that a golf putter have one or more removable and replaceable components.

In yet other applications, a player may further desire the golf putter to be easily assembled or disassembled “on the fly” and adjustability to a player desired configuration so that assembly/removal time is minimized. In addition, a player may desire the golf putter device durable but also conformable to use and to create minimal restriction to a user's movement. Furthermore, an improved golfing apparatus and methodology that is adaptable to either one-on-one coaching (e.g., player and instructor) and/or player alone golf putter practice activities.

Thus, what is needed are improved golfing apparatus and methodology that permits easy initial configuring and reconfiguring, i.e., provide adaptability, and upgrade capability so that the same unit be utilized (or added-on to) if new functionality is desired. Furthermore, such improved apparatus and methods would also ideally allow a person other than a professional or licensed personal to adjust or retrofit the golfing device, correct player perception errors and consistently provide a guide for aiming the putter without having to change a player's perception of a target location. Finally such improved apparatus and methodology should permit creation of user-customized golf putter configurations and customized fit and appearance of the golf putter as well as new patterns requiring minimal efforts, e.g., minimal adjustment or removal and replacement or adaptation of existing components, and provide more repeatability and correct alignment than conventional golf putters.

SUMMARY OF THE INVENTION

In a first aspect of the invention, a methodology is disclosed that involves a player and a coach working together to reduce an effect of parallax when a player putts a golf ball toward a target golf hole. In one embodiment, a player addresses the ball and initially aligns a player chosen single alignment marker of a multi-alignment marker to align a golf club face to a target golf hole. In one embodiment, the player chosen alignment marker aligns the golf club face to strike a golf ball toward a target golf hole.

In one embodiment, coach positions himself behind the player to view an orientation angle of golf putter. In one variant, coach faces player's forward direction swing area (and/or rear area) and views orientation angle of golf club face relative to golf ball and projected line of putt. The coach provides feedback. The feedback may include, in one embodiment, affirm a player's chosen alignment marker of the golf club face. In one alternative embodiment, the feedback may include a suggestion of an alternative alignment marker, e.g., coach chosen alignment marker. After selection of one or more alignment marker positions and in a trial and error method to produce repeatable correct alignment of the line of putt, a selected alignment marker is marked or recorded or remembered for use in future putting situation.

Advantageously, based each player's unique visual capability (e.g., right and left eye balancing and binocular vision capability and positioning of each eye in a person's face) and perception of golf putter face angle, the selected alignment marker provides a proper angle (orientation) for future play on a golf course.

In one embodiment, a modular replaceable top of the body includes an alignment marker layout substantially matching that of the selected alignment marker. In one embodiment, the modular replaceable top of the body portion includes a fastening apparatus, for instance, that connects detachably with one or more mating connectors to secure the replaceable top of the body portion to the golf putter. In one variant, the mating connectors are mating tabs or fasteners that removably lock with each other upon being pressing into or fitted into one another.

In a second aspect of the invention, a methodology is disclosed that reduces effect of parallax while player is putting toward target golf hole. In one embodiment, player addresses the ball and initially player aligns chosen single alignment marker of multi-alignment marker golf club body to target golf hole. In one embodiment, player chosen alignment marker is aimed along the line of putt resulting in a player perceived off-perpendicular putter face. Player receives feedback as to correct putter face angle after choosing an alignment marker. If the golf putter is off alignment with line of putt, e.g., left or right of a line of putt, a player chooses an alternative alignment marker (e.g., next alignment marker) on replaceable, multi-alignment marker golf club body until consistently able to properly align putter face to the line of putt.

Continuing with this aspect, upon successful repeated alignment, replaceable face portion is chosen that has alignment marker layout substantially matching that of player chosen alignment marker.

These and other embodiments, aspects, advantages, and features of the present invention will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art by reference to the following description of the invention and referenced drawings or by practice of the invention. The aspects, advantages, and features of the invention are realized and attained by means of the instrumentalities, procedures, and combinations particularly pointed out in the appended claims.

Overview

In one salient aspect, the present invention discloses apparatus and methods for, inter alia, configuring and utilizing a golf putter as well as provide custom capabilities, in one variant, to produce various configurations to conform to, for instance, a user's unique binocular vision, perception, right and left eye dominance, stereopsis that may be customized to a particular golf course terrain or topology. In particular, the present invention discloses an apparatus and process to provide a modular golf putter apparatus having a multi-alignment marker club top of body, for instance, to provide player and/or coach flexibility to fine tune level of golf play on an individual basis, e.g., golf putter device easily adjusted to match an individual's physical dimensions and visual perception to achieve a closer fit and function and provide improved accuracy and adjustability properties thereof.

Furthermore, the present invention discloses a golf putter apparatus applicable for professional and amateur alike play so players while participating in a golf outing or golf practice round (e.g., prior to tournament play, for instance, in USGA golf tournament) may have golf club adjustment and attachment capability, for instance, quick release fasteners that removablely attach alignment markers on top of body configurations attached thereto.

In light of the present invention, users may customize golf putter configuration and choose a desired level of golf play responsive to golf course or terrain or environment for a particular day or event; thus, this present inventive apparatus provides adaptability as compared with conventional, single alignment marker golf clubs. Furthermore, both coach and player individually or in unison reconfigure golf putter by choosing different alignment marker or changing insert on club top of body to an alternative material (steel, aluminum, graphite . . . ) to customize putter physical characteristics, e.g., adjust weight and balance of or minimize weight composite materials to improve user comfort (decreasing overall weight as compared to conventional non-configurable golf putters) and prevent unnecessary restriction of user movement (provide built-in flexibility).

Accordingly, the apparatus advantageously allows multiple configuration styles and supports many different system configurations through its ability to provide a significant flexibility of rapid adjustment to create new “customized” fit, e.g., using, for instance, fasteners including screw-in mating connectors, friction connection, magnetic attachment attachments, multi-shim attachments, and removable and attachable to provide quick-connects and disconnects.

Exemplary Extension Apparatus

Referring now to FIGS. 1, 5, 6, 7, 8, 9, and 10 include exemplary embodiments of the golf putter apparatus of the invention are described in detail. It will be appreciated that while described primarily in the context of golf putter apparatus to compensate for player perception, at least portions of the apparatus and methods described herein may be used in other applications, such as for example and without limitation applications including sports equipment manufacturing and testing setting environment to fine tune golf club balancing and customize “tailor” a feel and calibrate swinging capability of a prospective new golf club configuration in an automated or semi-automated assembly environment in accordance with physical attributes of a prospective golf participant, the environment that the new golf club configuration may experience, proposed methodology of swinging, providing functionality and interchangeability of piece parts, rehabilitating golf players who have physical limitations, physical ailments, and/or recovering from recent surgery or other sports injury, and the like.

Moreover, it will be recognized that the present invention may find utility beyond purely alignment and golf putter parallax concerns. For example, the “golf putter apparatus and hitting process” described subsequently may be conceivably modified to be useful in customizing physical properties and dimensionality of a hitting surface for golf ball so as to mitigate physical forces experienced by player when contacting a golf ball with putter club face, and the like. A myriad other functions will be recognized by those of ordinary skill in the art given the present disclosure.

Referring to FIG. 1, golf putter 100 is disclosed illustrating an assembled and modular configuration, respectively. Golf putter 100 includes grip 104 and shaft 102 having shaft conformal portion 106. In comparison to conventional perpendicular striking surface putters, golf putter 100 advantageously provides a high center of mass to maintain club face stability. Furthermore, shaft 104 and club face 108 may be constructed of, for instance, steel, aluminum, graphite, a composite polymer material, or the like.

On top of body of putter 100, multiple non-perpendicular alignment markers 110 through 116 located left of club face center 105 and alignment markers 120 through 126 located right of center 105 are utilized for alignment purposes. As illustrated in FIG. 6, modular golf plates 130 through 148 include one or more individual alignment marker(s), e.g., alignment marker 112. In one embodiment, alignment marker 132 corresponds to alignment marker 112 on the multiple non-perpendicular alignment markers, e.g., spaced apart and angled at two (2) degree increments. In one embodiment, modular golf plates 130 through 148 may have one or more individual alignment markers.

Referring to graphical illustrations in FIGS. 2 and 3, relative deflection or angle of golf ball determines if your ball will be off target if hit to the right or to the left of the correct alignment. In particular, one (1) degree angle alignment errors are very difficult to correct. However, a one (1) degree angle alignment error results in a one (1) inch deflection from center of target golf hole 152. Even though a golf hole has a radius of 2.125 inches and if this was the only error, the player would sink golf ball 151 into target golf hole 152. Unfortunately, other errors such as path error associated with putter back swing and through swing add additional errors, so when combined with angle alignment errors result in a significant overall error that results in missed strokes (e.g., higher golf scores.)

Referring in particular to FIG. 3, one (1) degree angle error results in one (1) inch error for a five (5) foot putt; thus, to improve player's golf game and lowers overall golf score, player 101 needs to recognize and correct even seemingly small angle alignment errors. In particular, angle alignment errors occur as a result of a player's unique binocular vision and apparent displacement between distance seen by right and left eye of the player and by changes in player's viewing positions.

As best illustrated in FIG. 4, player 101 is “standing astride” line of putt 104. In this example, player 101 faces target golf hole 152 with feet 143 a, 143 b on each side of a line drawn between player's feet, e.g., left foot 145 a, right foot 145 b, pointing toward a target golf hole 152. Continuing with this example, player 101 has head up and left eye 143 a, right eye 144 b both level looking toward target golf hole 152 along the line of putt 104.

Referring to FIGS. 5 and 6, player 101 is standing “side on” the line of putt 104. More specifically, “side on” line of putt 104 occurs where the position of player 101 is changed, e.g., player's head at a different angle, eyes, e.g., left eye 143 a, right eye 143 b, are not level when looking toward target golf hole 152 along line of putt 104, and player's feet, e.g., left foot 145 a, right foot 145 b, are pointed substantially perpendicular to line of putt 104. As best illustrated in FIG. 5, left eye 143 a dominate of player 101 aligns club face 108 to target golf hole 151 located at first location 154. As best illustrated in FIG. 6, right eye 143 b dominate of player 101 aligns club face 108 to target golf hole 152 at second location 156.

Using principles of the present invention, player 101 grasps golf putter 100 having a golf face 108 including multi-alignment markers (e.g., 110-116 and 120-126). In one embodiment, after swinging club face 108 using alignment marker 105, player 101 chooses and aligns an initial non-perpendicular alignment marker, e.g., e.g., initial non-perpendicular alignment marker 110, to hit golf ball 148 toward target golf hole 150. Advantageously, player 101 has multiple adjustment alignment markers proximally located to top of body above club face 108 to correct for visual perception displacement error 107 (e.g., binocular vision, stereopsis, and the like) associated with standing side-on (parallax) to line of putt 104.

Referring to FIGS. 7 and 8, coach 103 provides feedback to player 101 having golf putter 100 of FIG. 1 to compensate and align golf club face 108 to the target golf hole 152 to compensate for parallax situation illustrated in FIG. 4. Coach 103 observes a rear view of player 101 proposed putter addressing direction. For example, coach 103 may be a certified instructor, spouse, friend, or anyone else who can perceive positioning of golf putter 100 of player 101 where center marker 105, e.g., the line on top of body directly above sweet spot of the face and perpendicular to the face, is directed in relationship to player's 101 perception of where it is pointed. For instance, coach 103 may shout a suggestion to player 101 that correct alignment is left of current aiming position of player 101. In response to this suggestion, player 101 would choose a different non perpendicular alignment marker (e.g., markers 110-116 or 120-126) and ask coach 103 whether center marker 105 (e.g., the line top of body perpendicular to the face 108) is now aligned along line of putt 104. In response to this suggestion, player 101 would, if still off in alignment of line of putt 104, choose another different marker and repeat this process until marker 105 is directed along the line of putt. As such, player 101 aligns club face 108 perpendicular to line of putt, e.g., target line, which player 101 perceives as left (or right) of the target line.

In yet another embodiment, advantageously, from a rear view, a coach 103 provides quantitative stereopsis and/or qualitative steropsis inputs of golf ball 151 relative to golf club face 108 to improve its aiming alignment. Coach 103 located proximal to target golf hole 152 observes player 101 initial choice of alignment marker 110 (e.g. how to aim golf club face 108, which improve player 101 putting by overcoming other errors which have significantly less effect on how ball 151 rolls) for striking golf ball 151. In one variant, coach 103 observes an angle of golf club face 108 relative to golf ball 148 and projected path of golf ball 151 based on player 101 initial non-perpendicular alignment marker 110 selection.

A player 101 aims alignment marker 105 of putter 100 along line of putt 104 which indicates an initial direction of the player's perception the location of line of putt 104. In one embodiment, coach 103 provides initial (first) feedback to player 101 advising use of initial alignment marker 110 in response to player's initial perception of the relative location of the line of putt. Player 101 aligns (twists 109) club face 108 to a first corrected alignment marker, e.g., alignment marker 110, responsive to first feedback provided by coach 103 and/or based on observations of player 101 relative to displacement distance visually perceived from target golf hole 152.

Advantageously, player 101 positions club head 108 to align golf putter 108 with hole without loss of stabilization due to club's high moment of inertia partially resulting from curved neck 106 of shaft 102 connecting to club head 108. In one embodiment, coach 103 provides second (additional) feedback regarding choice of first corrected alignment marker 110 in response to the actual (not player perceived) direction alignment marker 105 and the face 108 are pointed. In yet other embodiments, coach 103 continues to provide feedback regarding player's choice of golf face 108 position and angling until satisfied with chosen position.

Player 101 aligns (twists 109) multi-alignment marker golf face 108 along a second corrected non-perpendicular alignment marker, e.g. alignment marker 112, in response to second feedback provided by coach 103. Afterwards, player 101 swings golf face 108 using second corrected alignment marker 112 to hit golf ball 151 toward target golf hole 152. Player 101 replaces modular, multi-alignment marker on body of club 108 with modular alignment marker (e.g., one of 130 through 148 modular alignment markers) relative to first and second corrected alignment marker 110, 112 respectively for future putting situations.

Advantageously, as compared with conventional golf putting, binocular vision of player 101 (e.g., parallax) where player 101 sees displacement of golf ball 151 from two different perspectives is corrected through choice of alignment marker or modular golf face by trial and error of player 101 and/or in combination with assistance of coach 103 without circumventing USGA rule 16-1, e.g., player 101 may not stand “astride” to the line of the putt and corrects for binocular vision. In contrast to conventional golf putter hitting a golf ball perpendicular, e.g., one alignment marker, on club face, a multitude of alignment markers provide compensation for parallax caused by desperate views by right and left eyes of player to determine a hitting player address angle for current as well as future golf play.

In FIG. 9 modular (e.g., interchangeable) alignment markers to right of the middle tilt to the left, e.g., markers 130, 132, 134, 136. The interchangeable markers to the right of middle tilt to the right from bottom to top, e.g., markers 140, 142, 144, and 148. If a marker position is not being utilized for a given player, then plates 137 or 138 are utilized. Advantageously, in contrast to previous conventional golf putters, modular alignment markers may be interchangeable so that golf putter alignment may be customized in accordance with player capability and unique visual perspective and depth perception of object location. For instance, golf putter 200 customizes play for player 101 to correct for right eye and left eye dominance and a disparate location between different viewing angles that varies a distance between golf ball 151 and target golf hole 152 using different alignment markers that are angled away from perpendicular on golf putter 100 to properly align putter 200 along a line of putt.

As best illustrated in FIG. 10, modular alignment markers 130-148 fasten or unfasten to golf putter 200 by one or more fasteners. For example, mating fasteners 145 a, 143 a on a back side of one of the modular alignment markers 130-148, e.g. modular alignment marker 137, for instance, inserted into mating fasteners 143 b, 145 a respectively on top of body of putter 200. Alternatively, other attachment mechanisms made utilized for modular alignment markers attachment including snapped into (using fasteners known to those skilled in the art) or friction or force fit or the like.

Advantageously as compared to conventional perpendicular only striking surface club face, inventive features include a High Moment of Inertia (H.M.O.I.). For instance, the H.M.O.I. is partially due to curved neck 106 near golf club face 108 as well as distributed weighted club head 108. As a result of H.M.O.I., golf club face 108 may be aligned (twisted 109) to various orientations of club face 108 and shaft advantageously provides high resistance to twisting during play (e.g., vertical axis stability is maintained) as player 101 addresses club face 108 along one of many alignment marks on top of body of putter 100. In addition, cutouts 111 and 113 (shown in FIG. 1) provide an improved weight distributed club head 108 to maintain H.M.O.I.

Advantageously, as compared with conventional golf putter alignment marking on a surface of the putter, in one exemplary embodiment, golf putters 100, 200 center marker 105 extending beyond alignment markers on the side thereof toward golf club face to increase player visualization of putter face orientation to that of the ball. Advantageously, an orientation and spaced-apart attachment in a semi-circular fashion at one end of alignment markers on side thereof (e.g., alignment markers 110, 112, 114, 116, 120, 122, 124, 126) main alignment marker (e.g., alignment marker 105) in a graduated fan-out arrangement provides player increased depth perception and spatial perception of target hole as compared to player utilizing an in-line alignment marker present on many conventional putters to align a club face with that of target hole.

Exemplary Methods

Referring now to FIG. 11, an exemplary embodiment of an individualized method 300 to compensate for aligning a player's golf club to a golf ball to hit a target golf hole is described. While described primarily in the context of the exemplary embodiments of apparatus 100 and 200 shown in FIGS. 1 and 4-10, it will be appreciated that the methodology presented herein may be readily adapted to many different configurations of apparatus 100 and 200 as recognized by those of ordinary skill in the art.

In step 305, player 101 positions golf putter 100 to align one of multi-alignment markers to an alignment marker to strike club face for golf ball 151. In step 310, coach 103 observes a rear in-line view of player 101 forward direction swing area. In one variation of step 310, coach 103 may observe an angle of golf club face 108 and a projected line of putt from in front of player 101.

In step 320, player 101 swings golf face 108 using alignment marker 110 to hit golf ball 151 toward the target golf hole 152 along line of putt 104. In step 325, coach 103 provides initial (first) feedback to player 101 regarding choice of alignment marker 110 in response to actual (not player perceived) direction alignment marker 105 and face 108 are pointed in relation to line of putt 104.

In step 320, coach provides second (additional) feedback regarding alignment marker 110 in response to relative location of the hit of golf ball 151 toward the target golf hole 152.

In step 325, player 101 aligns modular, multi-alignment marker along second corrected alignment marker 112 in response to second feedback by coach 103. Afterwards, player 101 positions modular, multi-alignment marker of golf face 108 along second corrected alignment marker to contact golf ball and hit golf ball toward target golf hole along line of putt 104. In one variation of step 325, using golf putter 200, player 101 replaces multi-alignment marks on top of body with one of modular golf markers(s) 130-148 with best of first and second corrected alignment marker (e.g., 110, 112) for future putting situations involving player 101.
